Abstract (en)
[origin: EP3509089A1] A method for effectively removing fluorine atoms remaining in a semiconductor fabrication chamber after cleaning the chamber with chlorine trifluoride is provided. The method includes exposing the inside of the chamber after semiconductor fabrication to chlorine trifluoride to remove an object to be removed remaining in the chamber and then thermally treating the inside of the chamber with at least one gas selected from the group consisting of nitrogen, argon, helium, and hydrogen. It is preferred that the exposure to chlorine trifluoride is carried out while monitoring the chamber inside temperature and that the chlorine trifluoride feed is ceased when the inside temperature decreases to a predetermined temperature.
